How Claude 4.8 Opus and Qwen3-VL-Plus differ
What the numbers mean in practice when choosing between Claude 4.8 Opus and Qwen3-VL-Plus.
-
Qwen3-VL-Plus is 92% cheaper on input tokens ($0.4 vs $5 per million), which adds up quickly in document-heavy workloads.
-
Qwen3-VL-Plus is 95% cheaper on output tokens ($1.2 vs $25 per million) - the bigger factor for tools that generate long documents.
-
Claude 4.8 Opus's 1M tokens context window is roughly 3.8x larger than Qwen3-VL-Plus's 262.1K tokens, so it can work across bigger codebases, contracts, or archives in one pass.
-
These are different kinds of model: Claude 4.8 Opus is a text model while Qwen3-VL-Plus is a vision model, so they often complement each other in a workflow rather than compete.
Strengths side by side
Where each model shines, according to benchmarks and provider positioning.
Claude 4.8 Opus
1. Modest but tangible gains across the board
- 69.2% on SWE-bench Pro (+4.9 points over Opus 4.7's 64.3%), 88.6% on SWE-bench Verified, and a 1,890 Elo on GDPval-AA - about 121 Elo ahead of GPT-5.5.
- Anthropic frames it as an incremental refinement of Opus 4.7 rather than a step-change release.
2. The most reliable agent model Anthropic has shipped
- The only model to complete every case end-to-end on Anthropic's internal Super-Agent benchmark, beating prior Opus models and GPT-5.5 at parity on cost.
- Leads CursorBench across every effort level with more efficient tool calling - fewer steps for the same intelligence.
- 84% on Online-Mind2Web and stronger OSWorld-Verified scores make it the strongest computer-use and browser-agent model Anthropic has tested.
3. New highs for professional and legal work
- Highest score ever recorded on Anthropic's Legal Agent Benchmark, and the first model to break 10% on its all-pass standard.
- Roughly a 4x improvement in honesty and calibrated uncertainty versus Opus 4.7 on Anthropic's evaluations.
4. Cheaper, faster controls
- Standard pricing holds at $5/M input and $25/M output, unchanged from Opus 4.7.
- Fast mode now runs at 2.5x speed for $10/M input and $50/M output - about a third of what fast mode cost on prior Opus releases.
- A new effort dial gives finer control over how hard the model works before answering.
5. Long-horizon agent workflows
- 1M token context window in beta and up to 128K output tokens.
- Introduces Dynamic Workflows (research preview) in Claude Code - Opus can write its own orchestration script and run up to 16 concurrent / 1,000 total subagents in a single session.
Qwen3-VL-Plus
1. Advanced OCR and extraction
- Reads receipts, documents, product photos.
2. Visual reasoning
- Understands diagrams and logical layouts.
3. Thinking + non-thinking modes
- Supports chain-of-thought.
4. Large 262K context
- Great for multimodal RAG.
